After dropping two passes in Ravens territory Monday night, Lions receiver Calvin Johnson wanted to watch the miscues on film. “You just want to get back and see it on film just so you could see exactly what you did,” Johnson said Thursday. “Just got to stay on it a little longer, turned my head too soon, can’t see it all the way in. Simple as that.” The errors may have been simple, but they were certainly costly. Johnson’s first drop was on a third-and-15 in the first quarter, and he was already past the first-down marker. Only safety James Ihedigbo stood between him and the end zone. “I feel like any time you catch the ball in the middle of the field on a defense, it’s just make one miss and you’re there,” Johnson said. The other drop was on a second-and-9 late in the second quarter, and again, Johnson was deep enough to convert the third down. The Ravens won, 18-16, on a 61-yard field goal by Justin Tucker in the final minute. “We could’ve left the field goal team on the sideline if we just handled what we had to do,” Johnson said. For the past few weeks, Lions wide receiver Nate Burleson has blamed losses on physical errors as opposed to mental mistakes, and Johnson echoed that Thursday. The Lions have lost four of their last five games.
